what are those serious issues?
Populism, they're prefer to break with traditions in exchange for followers.
interesting video, i can see difference between orthodox and catholic in their ritual
is the background music was actually from a church? i think orthodox church music more devout than catholic, imo

Yep, unfortunately it's a real liturgy from church. But it isn't a genuine catholic liturgy. This pseudo-ritual has been practiced by vatican-II sect.
I suppose that they mean countries, which are controlled by the communist parties. But really all of these countries are socialist republics.
Just a few examples to confirm:
http://en.wikipedia.org/wiki/ChinaGovernment Single-party socialist republic
http://en.wikipedia.org/wiki/VietnamGovernment Single-party socialist republic
is communist state really banned religion? i never go to vietnam, but i went to china once and saw many religious practical there
Far-left marxists are rejecting
any religion. According to their point of view, any religion it's a tool of control, which has the purpose to deprive people of their freedom. The majority of moderate socialists and communists are accepting religious practices as a part of society.
socialist and communist ideology should be one or it could be split?
It's something like C & C++.

Communist ideology incorporates socialist ideology, but not vice versa. Some socialists don't recognize a communist ideology, but communists recognize and using a socialist ideology.
Communist ideology sees the following way of the society development:
[various absolutist regimes here] <-> Free-market capitalism <-> State capitalism or Mercantilism <-> Socialism <-> Communism
With each step the role of the public ownership grows.
in my country, many people told me atheism and communism are the same

I think they will be very surprised by the existence of a christian version of the socialist and communist ideologies.
